Ultimate Tool for F&O Analysis & Charts - Tool with accurate OI data and 20+ charts for Option Chain, Open Interest (OI) Analysis, FII / DII data, Sectoral Indices & more to analyse live options market across Nifty, BankNifty & all F&O.
No credit card required · Trial Plan available · Setup in 3 minutes
OI, FII/DII, PCR, option chain, technical charts — all on different platforms. By the time you have a market view, the setup has moved.
OI on one tab, FII data on another, PCR on a third, and price charts in a separate window. Context gets lost switching between tools, and the market does not wait for you to reassemble your analysis from five different places.
A PCR reading means nothing without OI context. An OI spike means nothing without price direction. Disconnected data forces manual interpretation — and manual interpretation under time pressure is where retail traders make their worst calls.
Most free platforms show 15-minute delayed NSE data. In F&O trading, 15 minutes can be the difference between entering a breakout and buying the top of a move that already reversed. Real market analysis requires real-time data — and that means an NSE-authorised feed, not a delayed snapshot.
Nifty, BankNifty, FinNifty, 191 F&O stocks — tracking market direction across all of them without a unified platform means fragmented analysis and missed signals. A single view that brings all this data together is not a luxury for serious F&O traders. It is the baseline.
Understanding what each data type shows — and how they work together — is the foundation of informed F&O trading.
Analysis charts transform raw market data — OI, price, volume, PCR, institutional flows — into readable patterns. For F&O traders, these charts provide a structured framework for reading market direction before committing capital. The analysis charts and data for market insights on Stolo cover 20+ chart types in a single platform, updated in real time from NSE.
Open Interest tracks committed money, not just transacted money. A rising OI chart tells you which direction institutions are building positions in before price confirms it. Stolo's OI tools — option chain, strikewise OI, multi-strike OI, and OI charts — give you a complete, real-time picture of where large money is positioned across all F&O instruments.
Foreign and Domestic Institutional Investors move markets. When FIIs aggressively build or exit index future positions, Nifty and BankNifty follow. Stolo's FII/DII tracker gives you this data in real time during market hours, letting you align your options strategy with institutional flows rather than trade blindly against them.
No single chart gives you the full picture. The option chain tells you where money is positioned. The PCR chart tells you sentiment. The TradingView chart gives you price context. FII/DII tells you institutional direction. Using all of them together — in one platform with no tab-switching — is how professional F&O traders build a complete market view before placing a trade.
Every chart and data type an F&O trader needs — covering market data, OI analysis, technical charts, and institutional flows.

Start Analysing FreeBefore any market analysis begins, check Stolo's FII/DII tracker. If FIIs are net buyers in index futures, the broader market has institutional tailwind for the session. If they are heavy sellers, the directional bias shifts. This institutional context informs every subsequent analysis step — knowing the macro positioning before you look at any chart changes how you interpret the signals.
Open the option chain for Nifty or BankNifty and look for the strikes with the highest call writing and the highest put writing. These strikes define the market's likely range for the session. Call OI concentration marks resistance; put OI concentration marks support. This OI-backed level analysis is more reliable than price-pattern levels because it reflects actual committed capital, not just historical price memory.
Pull up the PCR chart and check where the ratio sits relative to its recent range. A PCR above 1.2 signals more put writing — typically a bullish market environment where option writers expect the market to hold or rise. A low PCR suggests bearishness from the same participants. Sentiment context from the PCR chart tells you whether to lean toward directional trades or expect range-bound activity.
Once you have an OI-backed support or resistance level and a sentiment read from PCR, switch to the TradingView chart for the instrument. Look for price approaching the OI-identified level and use a technical trigger — a candlestick pattern, a moving average cross, or a volume spike — to time the entry. The OI level gives you the zone; the technical chart gives you the precise moment to act.
Once in a trade, use Stolo's live market data views — sector movements, top gainers/losers, OI changes — to track whether the market continues in your expected direction. Falling OI on your instrument while you hold a position is an early warning that participants are exiting. Cross-reference with Stolo's OI analysis tools to stay ahead of position reversals before price confirms them.

Four data dimensions that, together, give you a market view no single chart type can provide on its own.
Open Interest tells you how many contracts are outstanding at each strike price and how that is changing. When OI builds at a specific strike, it signals a support or resistance zone where large traders are positioned. Stolo's OI tools — option chain, multi-strike OI, strikewise OI, and OI charts — give you a complete, real-time picture of where institutional money is sitting across Nifty, BankNifty, FinNifty, and all 191 F&O stocks.
Foreign and Domestic Institutional Investors move markets. When FIIs aggressively buy or sell index futures, Nifty and BankNifty follow. Stolo's FII/DII tracker provides daily derivatives and capital market data so you can align your options strategies with institutional direction — not against it. Available in real time during market hours, not just as an end-of-day summary.
The Put-Call Ratio is one of the most reliable sentiment indicators in options trading. A high PCR signals more put writing — typically bullish. A low PCR suggests bearishness. Stolo's live PCR Charts let you monitor this in real time alongside price and OI data. Pair it with Stolo's proprietary Options Snapshot to catch large OI shifts before they move the market and before most retail traders notice them.
No trade happens in isolation. Stolo's sectoral indices view shows you which sectors are leading or lagging the market, giving you macro context before any options trade. Combined with top gainers/losers and market movers views, you get a full-market perspective — so you are not making F&O decisions based on a single instrument's chart while missing a sector-wide shift.
